Hi,
Upgrading from 1.4-rolling-202311111230 to 1.5-stream-2025-Q2 which failed;
```
twan@rtr2# load
Loading configuration from 'config.boot'
vyos.migrate - ERROR - Error in /opt/vyatta/etc/config-migrate/migrate/dns-dynamic/1-to-2: Path [b'service dns dynamic address eth0 service'] doesn't exist
Traceback (most recent call last):

raise ConfigTreeError("Path [{}] doesn't exist".format(path_str))
vyos.configtree.ConfigTreeError: Path [b'service dns dynamic address eth0 service'] doesn't exist
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/vyos/compose_config.py", line 73, in apply_file
self.apply_func(func)
File "/usr/lib/python3/dist-packages/vyos/compose_config.py", line 60, in apply_func
raise ComposeConfigError(e) from e
vyos.compose_config.ComposeConfigError: Path [b'service dns dynamic address eth0 service'] doesn't exist
```
The config looked like this before upgrade;
```
twan@rtr2# show service dns dynamic
address eth0 {
rfc2136 PDNS {
host-name a.elajt.se
key /config/auth/pdns.key
server 10.1.1.153
zone elajt.se
}
}
```
I ended up deleting the section and then the migration worked.
While readding the section manually I noticed that the protocol most likely has been renamed from `rfc2136` to `nsupdate`, which should have, but does not, happen in [[ https://github.com/vyos/vyos-1x/blob/a1be2ee22cd058d5e18e6ef4fb3ec6468a38aa37/src/migration-scripts/dns-dynamic/0-to-1#L32 | 0-to-1 ]].
